custom layout instead hikashop_product_list

if we study how layout for hikashop_product_list work , we have the 4 choices : div, Table,list and inherit.

I have 3 questions about how layout is implemented in hikashop .

1) In the case of item product , HS team use a mix of X Y number so the CSS style selector look like
"hikashop_product hikashop_product_column_X hikashop_product_row_Y" without "," but with 2 space " " since we have 3 items . hikashop_product is there so it let us know the number of items using js XPath so it is usefull. I think we must have by default for each product a CSS id Name.
do you call the product id ike this <?php echo $this->row->product_id;?> ?


2) since the layout to use is a mix of "Product|Category ..." and "table|list|..." even there is some incompatibilities since categories don't support table . if i am not happy with the default structure create by the mix (so not happy only with the restricted choice of div /table ); is there a tutorial that explain after create a file call components\com_hikashop\views\product\tmpl\nodivnolist.php how this file must implemented and with code must be add to be handle by the backEnd ? .
For the problem i have now a better way will be to have an option to have structure worflow with no ul/li or table AND with no nested div.

3) is there a tutorial that show all relation beetween file locate in components\com_hikashop\views\product\tmpl\**.php
Many call of same fonction with differents parameters
if($this->params->get(' ')
$this->setLayout(' ');
echo $this->loadTemplate();

I don't want to use override ( Since layout are locate under compoment we can override thoses files right ? )
i begin to find hikashop very easy to use ... the CSS layout and style is for designer ( boostrap ll help css beginners) ...keep focus on php /joomla functionnalities !!
